Data-Driven Reactive Power Optimization of Distribution Networks via Graph Attention Networks

Reactive power optimization of distribution networks is traditionally addressed by physical model based methods, which often lead to locally optimal solutions and require heavy online inference time consumption. To improve the quality of the solution and r ...

Stability of the Faber-Krahn inequality for the short-time Fourier transform

Joao Pedro Gonçalves Ramos

We prove a sharp quantitative version of the Faber–Krahn inequality for the short-time Fourier transform (STFT). To do so, we consider a deficit which measures by how much the STFT of a function fails to be optimally concentrated on an arbitrary set of pos ...

Dynamics analysis for DC transformers integration in hybrid AC‐DC power distribution networks

Drazen Dujic, Andrea Cervone, Jules Christian Georges Macé, Max Dupont, Renan Pillon Barcelos

In AC/DC power distributions networks, power converters are interfacing buses to ensure DC voltage regulation and power distribution. Active front ends are used between AC and DC buses and two typical control schemes that can be implemented are voltage reg ...

DC Transformer Impact on Voltage Dynamics in Hybrid AC-DC Power Distribution Networks

Drazen Dujic, Andrea Cervone, Jules Christian Georges Macé, Max Dupont, Renan Pillon Barcelos

AC/DC power distribution networks use various types of power converters to interconnect their buses, active front ends between AC and DC buses, and DC transformers between DC buses. Different active front end control methods, like voltage or power regulati ...

Harmonic Power-Flow Study of Hybrid AC/DC Grids with Converter-Interfaced Distributed Energy Resources

Mario Paolone, Yihui Zuo, Andreas Martin Kettner, Johanna Kristin Maria Becker

As the share of Converter-Interfaced Distributed Energy Resources (CIDERs) in power distribution systems increases, hybrid AC/DC distribution systems are drawing more interest. Indeed, CIDERs usually rely on DC power and hybrid AC/DC grids with few Network ...

Distributed Scheme for Line Overload Mitigation With Linearized AC Power Flow

Ping Hu, Li Ding

The transmission overload after a disturbance poses significant security risk to the power system. Once it happens, an efficient remedial action must be taken to relieve the line overloads as quickly as possible. The line overload mitigation problem become ...

Expansion planning of active distribution networks achieving their dispatchability via energy storage systems

Mario Paolone, Ji Hyun Yi, Katarina Knezovic

This paper presents a combined framework for power distribution network expansion planning (DNEP) and energy storage systems (ESSs) allocation in active distribution networks (ADNs) hosting large amount of photovoltaic (PV) generations and loads. The propo ...

On the Solution of the Optimal Power Flow for Three-Phase Radial Distribution Networks With Energy Storage

Jean-Yves Le Boudec, Cong Wang, Eleni Stai

We study a multiperiod optimal power flow (OPF) problem in unbalanced three-phase radial distribution networks with batteries. To address this problem, we first take the resistance-line battery model that treats lossy batteries by adding resistive lines an ...
